Revealed in February of 2020, the UMS Skeldar / UMS Aero Group "V-150" is a dimensionally smaller, lighter weight, and less expensive form of the earlier V-200 (detailed elsewhere on this site). Both are designed along the lines of a rotary-wing (helicopter) Unmanned Aircraft System (UAS), showcasing the inherently useful Vertical Take-Off and Landing (VTOL) capabilities of a traditional helicopter without the manned commitment. The designation "V-150" refers to its Maximum Take-Off Weight (MTOW) of 150 kilograms and follows both the V-200 and V-350 air systems in development.
As finalized, the V-150 sports a running length of 10.5 feet and a rotor diameter of 11.5 feet, making it compact enough to be suitable for operations off of modestly-sized naval warships. Beyond its obvious military value, the type is also seen as a good fit for the oil and gas industry, as a general UAS training solution, in the Search and Rescue (SAR) role, the SIGnals INTelligence (SIGINT) role, and border protection / drug interdiction - any service requiring a relatively compact, easy-to-operate / easy-to-maintain UAS product.
At the front-end of the fuselage (in the "chin" position) is housed an Electro-Optical (EO) / InfraRed (OR) optics set offering real-time video processing / moving target detection to commanders on the ground. The aircraft can also be outfitted with a variety of mission-equipment covering enhanced (protected) communications and intelligence-gathering. The equipment is spread across two bays, the forward one rated for up to 12 kilograms and aft one for 30 kilograms. Beyond this, the V-150 is also seen as a modest re-supplier with its payload capable of transporting goods to forward-operating elements.
The V-150 has been tested with a gasoline-fueled turbine engine though production forms will feature a heavy-fuel rotary piston engine. This powerplant drives a three-bladed main rotor blade seated atop the fuselage as well as a two-bladed tail rotor unit facing starboard at the extreme end of the vehicle. Currently, the aircraft has a mission endurance window of about 2.5 hours when carrying a 12 kilogram payload aloft. A mission endurance of four hours is the target for future revisions on the product. It can operate in all-weather conditions during the day or in night time hours.
The vehicle's fuselage is streamlined as much as possible for aerodynamic efficiency and houses all pertinent systems. It sits on the ground by way of twin landing skids affixed to the bottom of the fuselage through a four-point system.
The V-150 is being marketed alongside the larger, more expensive V-200 series which was developed as a maritime unmanned helicopter system itself. The V-200 has seen operations with Canada, Germany, Indonesia, and Spain to date (2020).
